# UTF-8-Validator
Developed as an assignment for the Introduction to Programming class at the National Kapodistrian University of Athens by Angelos Sfyrakis.
# What is UTF-8- ?
UTF-8 is a variable-width character encoding used for electronic communication. Defined by the Unicode Standard, the name is derived from Unicode (or Universal Coded Character Set) Transformation Format – 8-bit. UTF-8 is capable of encoding all 1,112,064 valid character code points in Unicode using one to four one-byte (8-bit) code units. Code points with lower numerical values, which tend to occur more frequently, are encoded using fewer bytes.
# Prefix code
The first byte indicates the number of bytes in the sequence. Reading from a stream can instantaneously decode each individual fully received sequence, without first having to wait for either the first byte of a next sequence or an end-of-stream indication. The length of multi-byte sequences is easily determined by humans as it is simply the number of high-order 1s in the leading byte. An incorrect character will not be decoded if a stream ends mid-sequence.
# Compilation and Input
-To compile:
```bash
gcc utf8validate.c -o name
```
Input must be a text file for the program to run.
-To run:
```bash
./name < text_file_name
```
# Notes
In this assignment students were given instructions not to use arrays(strings included).
